Assets NOT recompiled because Xcode skip run Copy Pod Resources

[Whirlwind]

CP add some Input Files and Output Files to Copy Pod Resources in Build Phases. And Xcode will not run again if the Input Files and Output Files not be changed, include their contents are not changed. It is good job.

But, there are a logic which search assets will not be run again in the Copy Pod Resources script:

  OTHER_XCASSETS=$(find "$PWD" -iname "*.xcassets" -type d)
  while read line; do
    if [[ $line != "${PODS_ROOT}*" ]]; then
      XCASSET_FILES+=("$line")
    fi

There is a strange logic in the CP:
CP find all assets in my project directory, then run actool to compile my project's assets and Pod's assets together. actool will generate a Assets.car in xxx.app, and instead of origin Assets.car which be generated by Xcode.

eg:

My Projects: Assets.xcassets and IM.xcassets
Pods: ShareSDK.xcassets

Xcode will compile Assets.xcassets and IM.xcassets to Assets.car first. but it is a small file.
The Pod will recompile Assets.xcassets, IM.xcassets and ShareSDK.xcassets to a bigger Assets.car to instead of the small one.

It is OK, if there is NOT the Input Files and Output Files....

When the Input Files and Output Files not be changed, Xcode will skip the script.
If I update the Assets.xcassets, the Xcode will recompile the Assets.xcassets and IM.xcassets to a small Assets.car to overwrite the bigger which generated by Pods. But the Pod will not run the script again. So I will lose the ShareSDK.xcassets in my Assets.car.

I think the assets logic should be a Independent script.

Could you understand what I said?

Could you understand what I said?

Kind of...I can see a problem potentially but would like to see a sample app here demonstrating the issue 100%.

[Whirlwind]

The Demo is very easy: https://github.com/Whirlwind/CocoaPodsTestAssets
First, build and run the MyApp, you will see a imageview in simulator. Then, please add any image to the Assets.xcassets in the MyApp. Run again, you will lost the image in the imageView!

Test by Cocoapods v1.5.2

[dnkoutso]

definitely a bug. investigated will be a bit tough to fix. See more here #7779 (comment)

I meet this issue too， with envi:

• cocoapods 1.6.0 beta1
• xcode 10 release
  did it resolved?

@dnkoutso I experienced the same issue with a fresh project now and Xcode 10 when creating a sample project for #8136.

For everyone who is curious of how to reproduce the issue, I have setup a detailed sample project here:
https://github.com/Fab1n/PodResourcesBug

The sample project actually shows 2 recent issues regarding asset catalog compilation.
For this issue here you will need to check out the first bug.

The test procedure is written in detail in the repo's README.md

I meet this issue too， with envi:

cocoapods 1.1.1
xcode 10 release
did it resolved?

[dnkoutso]

I have a fix for this.

[dnkoutso]

@Whirlwind I have a fix on branch xcassets_revamp can you try it?

[dnkoutso]

actually its not there yet.
